to pull a kanye is to rudely interupt someone
esp. when by doing so you take the moment away from them or steal the limelight
this is derived from MTV's VMAs 2009 when Kanye West famously got on stage during Taylor Swift's acceptance speech for 'best female artist video' and took the microphone from her stating that Beyonce instead deserved the award.
Paul: yo did you see that dude pull a kanye last night?
Steve: yeah he really ruined the night for that little girl
I was at a really boring awards ceremony last night and almost couldn't resist getting onstage to pull a kanye
